The interfaces are: asynManager provides services for communicating with a device connected to a port. asynCommon is an interface that must be implemented by all low level drivers. The methods are: • report - Report status of port. • connect - Connect to the port or device. • disconnect - Disconnect from the port or device. asynTrace is an interface for generating diagnostic messages. asynLockPortNotify is an interface that is implemented by a driver which is an asynUser of another driver. An example is a serial bus driver that uses standard serial support. asynManager calls asynLockPortNotify whenever it locks or unlocks the port. asynDrvUser is an interface for communicating information from device support to a driver without the device support knowing any details about what is passed.
